Thanks for the reply. MobX does look interesting. I recently watched Preethi Kasireddy's presentation comparing MobX and Redux (https://www.youtube.com/watch?v=76FRrbY18Bs), which I'd recommend watching to anyone in my shoes. A couple of things give me pause about MobX. One, it doesn't quite have the inertia or industry buy-in that Redux has. It's popular, but in terms of GitHub stars, it's less than half as popular as Redux. Alone this isn't super meaningful, but if you look at the contributors page for MobX, it seems like it's predominantly the work of one person. Again, not super meaningful on it's own, but Redux seems to have the benefit of a larger group of core contributors working on it and larger community support. Just circumstantial evidence, but I feel like it's a safer bet for client work on this front. There's value in following the well worn path. The other thing that gives me pause about MobX is this opinion I've heard a few times and you've just re-iterated, which is that MobX is easier to work with and possibly better for smaller projects, but Redux scales better. I'll concede, it's possible I need to quit whining about the funkiness of Redux and live with it for awhile. It might grow on me. :)

You might want to fish up the MobX users list in one of its github issues. The users list is huge, and includes rather large projects such as Battlefield 1's UI, CoinBase and I think the new MS Outlook to name just a few.
